Fellow forum member marwan from the UAE has graciously obtained the part numbers for the front left and right carbon fiber splitters that were announced by BMW Performance for our M3s recently. I typed the numbers into Tischer's parts catalog, and they came up as available for purchase ($250 each).

51190404056 and 51190404057

marwan is getting the part number for the rear CF spoiler from BMW Performance in the next 24 hours (hopefully).
